Mischa Barton doesn’t come out much to mix and mingle, but when she does show up, she still manages to command attention. The 25 year-old model/actress recently surfaced at the opening of Vivenne Westwood’s Los Angeles boutique, and while her tresses are tattered and her metallic frock is quite questionable, her skin happens to be the real star here. She hasn’t looked this healthy and youthful since her days as Marissa Cooper on The O.C. (Not sure what’s she doing, but she should absolutely keep it up!)

For a luminous, youthful dermis, always abide by the following five: 1) Wash your face twice a day, and never slumber in your slap; 2) It’s never too early to start anti-aging; 3) A weekly exfoliating mask can help keep your complexion completely clear; 4) A good moisturizer is your first defense against premature wrinkles; and 5) Don’t forget about your lips! Below, a few of our favorites—and your new clear skin Rx.
